Because of this the tool joints mentioned.

I claim:

1. A =wrench comprising a head with a readily accessible tilthe wrench becomes fully seated thereon and its jaws then embrace the object as completely as they are capable of doing. Then by turning the wrench in the direction of the 'arrow, the grips will .turn slightly to firmly grasp the object, and continued movement in the arrow direction will result in turning the object as may be desired. The wrench can then be, oscillated and at each backward movement the grips. will slip on the tool 'oint and at each forward movement and turn the same.

The or flanges of the head, one of which is shown at 16. This pivot is to one side ofthe center line of the wrench, and at the other side of this centerline the handle is' connected to the head of the wrench by a pin 17 working in an opening 18 in the ears or flanges of larger diameter than the pin, so that the handle may be manipulatedto deliver a hammer blow on the head of the wrench moved rapidly in the arrow direction. The wedge is arranged adjacent the joint between the handle and the head of the wrench and the head has a slightly ofiset portion 19 to afiord a vertical bearing face for the slight ofli'set arrangeoperating the wedge is for adjustment. The wrench may? be employed in situations or with objects other than ment the bolt for rigid jaw and an opposed pivotedjaw, means for adjusting the pivoted aw, and grips carried by the' rigidand pivoted jaws, one of said grips being pivotally mounted, substantially as described.

2. A wrench comprising ahead with a rigid jaw and an opposed pivoted jaw, means for adjusting the pivoted jaw, and grips carhandle is pivoted at 15 between ears when it is 3. A wrench comprising a head with a rigid jaw and an opposed plvoted jaw, means for adjusting the pivoted jaw, and grips carried by the rigid andpivoted jaws, there being two spaced apart grips on the rigid jaw and a pivoted grip near the end of the pivoted jaw.

4. In combination in a wrench, a head, a jaw pivoted to. the head intermediate of its lengt means between the tail portion and the head consisting of a wedge movable lengthwise of the head, and a screw also extending lengthwise of the head for adjusting and holding the wedge, substantiall' as. described. 5. In com ination in a wrench, a head having a rigid jaw, an opposing pivoted jaw, and an adjustable wedge between the rear end of the pivoted jaw and the head bearing with one face-upon the head and with its opposite face upon the jaw, substantially as described. 1 a

6. In combination in a wrench, a head having a rigid jaw,'a lug extending out from the edge of the head,. a jaw pivoted intermediate of its length upon the lug, a wedge member between the rear part of the pivoted jaw passing through the wedgeand into thelug, substantially as described.

7. In combination in awrench, a head having a rigid of less widt movable jaw recessed and pivoted thereto, rear part of the movable law and the head, and means for operating the wedge. y In testimony whereof, I affix my si CLARENCE .E. R ED.
